Most people believe that rosin is unimportant and that all of them are the same...but this one is different it is a lot better...your tone quality is a lot softer not in volume but like tone wise...I know many people who use it...Rosins vary in price but they last a long time as long as you donÆt drop or crack them. So you might as well get a nice one so you can you it for a really long time.
